Abstract
A converter for satellite communication reception which reduces signal losses and has a simplified assembling work is disclosed. In operation, orthogonal bipolarized signals transmitted from a satellite are branched into two propagation paths within a waveguide. A horizontally polarized wave is caused to proceed in a first propagation path, while a vertically polarized wave is caused to proceed in a second propagation path. A pair of probes supported by a circuit substrate and fitted to a case have tips that extend into two waveguides to receive the respective signals. By integrating the waveguide and the case by fastening, the first propagation path and the first waveguide are positioned to communicate with each other, as are the second propagation path and the second waveguide.
